Be it known thatI, PIERRE A. IIUMBERT, of the city and county of SanFrancisco, and State of California, have invented an Improvement inSinking-Pumps; and I do hereby declare the following to be a full,clear, and exact description thereof.

My invention relates to that class of pumps used in mines, and adaptedto be lowered as the shaft is sunk to keep it free of water; and itconsists in a pump suspended in the shaft and driven by an endlesstraveling wire rope or cable passing down the shaft and forming a looparound a suitable sheave or sheaves located at a pointabove, and adaptedto be lowcred to shorten the loop and allow the pump to sink Withouthaving to splice the driving rope or cable.

It consists, further, in the novel construction of parts, thearrangement of sheaves, the means for suspending and lowering the uppersheaves, for securing the-pump, and extensible suction and dischargepipes, the latter provided with peculiar valves, in means for alteringthe stroke of the pump, and in other details of construction, all ofwhich I shall hereinafter fully explain, reference being bad to theaccompanying drawings, in which Figure 1 is a side view of mysinking-pump apparatus, showing it in a shaft of a mine. Fig. 2 is a topview of same. Fig. 3 is a de- Fig. 4 is a similar view of sheaves K K.Fig. 5 is an end view of clamp S. Fig. 6 is a side view of same. Fig. 7is a vertical section of the dischargepipe; Fig; 8 is a vertical sectionof eccentric crank and pin.

The object of my invention. is to provide a sinking-pump which isadapted to be driven by an endless traveling wire rope or cable, andwhich, in its adjustments as the shaft is sunk, will not require thestoppage of the rope nor its splicing to lengthen it, and can thereforebe lowered without loss of time and without inconvenience.

A is the shaft of the mine, on the under or lower wall of which are laidtracks a a, for the various wheeled trucks hereinafter described. 13 isone of these trucks, which carries .the pump 0. The lower end of thistruck is provided with dogs b, adapted to engage with the and hold thetruck B firmly to its place whervever adjusted.

E is another truck on the same track, but higher up in the shaft. Theupper end of this truck is provided with safety-dogs e, which come intoaction only in case of a brealgwhen they prevent the truck from falling.

On the track a is a third truck, F, having at itsupper end safety-dogs fand at its lower end dogs f,which suspend and hold the truck whenadjusting the others, as I shall explain, or which save it from fallingin case of a break. This last truck carries a Windlass, G, from which awire rope or cable, H, extends up .the shaft to a guide sheave, h, overwhich it passes down the shaft again to the top of I truck E, to whichit is secured. This rope is for the purpose of suspending truck, E anddrawing upon it, so that the driving-rope .which connects the trucks Eand B shall remain tight, thus taking up the slack. This will be betterseen after the description of the drivingrope' and its course, which Inow proceedto explain.

Upon truck B is mounted a double-facedsheave, I, Fig. 2, in front ofwhich are two sheaves of equal diameter, though both are of smallerdiameter than sheave'I. One of these sheaves, J, Fig. 3, is keyed fastto the shaft, while the other, J, is loose on the shaft, and is held toits place by a collar, j.

Upon the lower end of truck E is a shaft, is, upon which are looselymounted the sheaves KK, Fig. 4:, the bearing of which is in\ the hubs ofthe sheaves as they turn on and not with the shaft. These sheaves are ofequal cliameter about equal to the diameter of the sheavaL, mounted justabove them, and which is set on an angle, as shown in Fig.2. Above thisis a sheave, M, of a diameter sufficiently great to carry the rope overthe sheaves just described. Above this, and overlapping at one side, isa sheave, N.

O is an endless wire rope or cable, which is supposed to be driven bysuitable mechanism ICO at the surface, (unnecessary to show here,) andthrough which the power is transmitted to operate the pump. The wirerope passes down the shaft, as shown by the descending arrow, taking thetop of sheave M, which carries it over sheaves L K and sheave J below tothe inner face of sheave I. It thence passes around said face of sheaveI, up between it and sheave J, over the top of sheave J, by which it isdirected up the shaft to sheave K. It passes over the top of ,thissheave and down between it and inclined sheave L, the bottom of which itstrikes. It is thence carried around and to the top of said sheave, and,directed by its inclination, passes down to the outer or near face ofsheave I on the lower truck. By this it is carried around, under, and upagain beside itself between the sheaves I and J, over sheave J, upwardand inclining downwardly to the bottom of sheave K; thence, missing thelower portion of inclined sheave L, it passes up to the top of sheave N,and thence up the shaft, as indicated by the ascending arrow. The ropein its course is kept clear of itself, by which all chafing is avoided,and throughout its length it is held up from the lower wall of theshaft, so that it cannot be interfered with in any manner. This holdingup of the rope is very necessary in an inclined shaft such as I havehere shown; but in a vertical shaft it would not be important, and Icould therefore dispense with such sheaves of the arrangement as areused only to direct and keep the rope near the top.

The reason for the fast sheave J and loose sheave J 'is as follows: Theendless rope passes over the tops of each in the same direction, and ifboth were made in a single sheave, or both keyed to the shaft, the leastvariation or difference in the circumference of their faces would causea drag on the rope; but by having one of them loose this variation is ofno importance, as the loose one can regulate itself to the speed of theother.

The reason for the loosely-mounted and independent sheaves K K is thatthe course of the endless rope over one is in a direction 0pposite toits course under the other. By the course of the driving wire rope, asdescribed, it will be seen that by reason of going back to the sheaveson the truck or frame E a loop is formed in the rope. This loop providesfor the necessary extra length of rope in sinking the pump. If the pumpwere driven directly by an endless wire rope or cable extending from thesurface to the pump, it is evident that whenever the pump would have tobelowered as the sinking of the shaft progressed the driving-rope wouldhave to be cut and a new length inserted and spliced. This operationwould take time and occasion the stoppage of pumping operations sofrequently that the device would be impractical; but I have provided forrunning a length of driving-rope sufficient for any desired depth bymeans of taking up the surplus in a loop, by the shortening of which thepump may be lowered during a continnance of the operation untilthe loopis lessened to its limit. In order to explain this more fully, I willillustrate it in connection with the drawings. Suppose the pump has beenoperating from the position shown during a time sufficient to sink theshaft to a depth which carries the water below the suction of the pump,then it has to be lowered until its suction can again reach the water.The ordinary course would be to cut the driving rope and splice it, toallow the pump to be lowered; but instead of having to do this, andthereby lose time, I simply lower the frame or truck E, thus slacking upthe loop of the rope, which allows the pump to be lowered to the desiredpoint, and this adjustment or lowering of the pump can continue untilthe loop is shortened to its limit, which takes place when the truck Ereaches the truck B. This operation of lowering can be done rapidly withthe least possible loss of time. In a small shaft, and with alightpumpand short driving rope or cable, I could allow the pump frame or truckto remain suspended in the shaft with no other support than that whichthe driving-rope itself would afford, the upper frame or truck beingtemporarily secured, in which case the weight of the pump and framewould tighten the driving-rope to take up the slack, and I could thusdispense with independent means for taking up the slack; but withheavier machinery and a deep er shaft this would not be practicable, asthe pump would be too heavy for the rope and would be liable to have toomuch vibration. Therefore Ihave the tightener frame or truck F, as Ihaveheretofore mentioned. I shall now describe it more fully.

Upon the windlass G on the truck F is a strap-brake, 1?, having handle1). The windlass has also a large gear, Q, which meshes with a pinion,g, on a shaft, q, which also carries a gear, q, meshing with a pinion,1-, on a shaft, It, adapted to be operated by a crank, 1'.

Under a beam of the truck F, Fig. 5, is a rope clamp or grip, S,consisting of two halves provided with suitable seats, through which thesuspending wire-rope H passes. This clamp is tightened by bolts 8, Fig.6, and is secured to a slide, .9, mortised in the beam, Fig. 5, in orderto allow the rope to adjust itself to the proper plane from the sheave hto the windlass. \Vhen the rope is thus gripped, the winding drum isrelieved. The tightener-trnck F is to be made heavy enough to draw up onand suspend the truck E, and is itself suspended, when its dogs arereleased, by the weight of the latter truck and its connection with .thepump-truck B, which is firmly placed below by means of its dogs. Thisupward tension on the truck E therefore takes up the slack in thedriving-rope.

When the pump has to be lowered, I first seize the lever I of thewindlass, unclamp the rope H from grip S, and lower the truck F downuntil it rests on its upper dogs, and its IIO lower dogs f drop intoplace. ThenI loosen nuts (I to slacken up the lower dogs b "of truck B,which I knock out, after which I wind up on the Windlass G until I canfree Then I stop the Windlass G, let the dogs b D of truck B fall in,and tighten up the upper dogs to. secure said truck. I then loosen thedogsf' of the truck F and wind up on the Windlass, raising the saidtruck F untilits dogs f are free, and then I clamp the rope again, whenthe truck is suspended, and its weight will draw up on truck E,suspending it, and take up theslack ofdriving-rope again. This operationis repeated until the loop of the driving-rope is shortened to itslimit.

In order to make the adjustments of the pump as few as possible, and torender it unnecessary at every adjustment to fit on a length to thedischarge-pipe, I make both the suction-pipe T and the discharge-pipe Ttelescopic by means of the slipjoint shown in Fig. 7. When the shafthasbeen so deepened as to lower the water beyond the suction, in stead ofimmediately lowering the pump, I simply lengthen out the slip-joint ofthe suction until it reaches its extent; and when the pump has'beenlowered, instead of having immediately to add a new length to the dis-.charge-pipe, Ilengthen out'its slip-joint; but

when it does become necessary to add to the discharge I have providedfor the continuous operation of the pump during the work of fitting thenew piece. In this connection I provide also for relieving the pump ofthe weight of the water-column, so that in the operation of lowering aconsiderable weight is removed, making the handling of the tightenerthat much easier.

In Fig. 7, which may now represent the dis charge-pipe U, is the usualforking-valve, by means of which the surplus water which the pump may betaking over and above the necessity of the case is carried back into thesump. Below this valve, in the dischargepipe, is an upwardly-swingingclack-valve, V. Below this is an outlet-valve, WV, which I call thelowering-valve. When thepump is being lowered, the valve WV is opened,and all the water passes out through it, and is conducted into the sumpagain. The clack-valve, being relieved, falls down and supports thecolumn of water above, thus relieving the pump of its weight; but when anew piece of pipe has to be added above, then, to protect the workmenfrom occasional splashes through the valve, I have the lever '0,operated by a may not be desirable.

The mechanism by, which I transfer the power of the endless driving-ropeto the pump is as follows: Upon the end of the shaft 'i upon which thesheave I, Fig. 2, is mounted is a pinion, a, which meshes with a gear,X, to which the crank-pin Y is attached. pitman 3/ of the pump isconnected with the cranlcpin. In order to regulate the throw of thecrank and pin and operate the pump to whatever extent is required, Ihave the device shown in Fig. 8.

Z is a disk keyed eccentrically onto the shafti beside the face of thegear X. This disk has a rim, z,with a lip, 2, extending inwardly andforming a groove.

Z is a disk, having a lip, s on its rim. This is laid upon the disk Z,and is bolted to it by the bolts 20. Upon the disks Z Z is fitted aplate, 0, which is adapted to turn thereon, being guided by a smalltongue and groove at l, and secured in any position by means of bolts Z,the heads of which have been previously seated in the groove formed bythe lips of the disks Z Z, and whose bodies extend 'up between thelipsand through the plate 0. The crank-pin Y is secured in this plate,as shown. By loosening the bolts Z the plate 0 may be turned on itsbearing to give the pin Y more or less throw, according to its positionwith relation to the shaft 2'. By tighten ing up the bolts again the pinmay be fixed in the desired position.

The

The necessity for altering the stroke of the pump herein is as follows:The endless wirerope by which/it is operated is itself driven by thesame power andat the same rate of speed as the endless rope which drivesthe stationary pumps, not herein mentioned. Now, when the water in thebottom of the shaft gets low, it is not advisable to run the sinkingpumpto its. fullest capacity, and its work must be lessened in some manner.To do this by slowing down the driving-rope would affect similarly allthe stationary pumps,which Instead of this, the mechanism I havedescribed enables me to accomplish the result of making the sinkingpumpdo more or less work without changing the speed of the driving-rbpe; butthe advantage of such a deviceis'not confined to a sinking-pump, butapplies to the station-pumps, or any pumps driven by an endless cable,for it is never. advisableto reduce the speed of the cable too much, asthe friction on the sheaves would be lessened and much power wasted.
